    Big Omega with a plus/minus subscript

    I'm not quite sure which section asymptotics goes in, but I doubt it is calculus.

    I've come across a statement from an article written in the 80s that says \frac{\sigma(n)}{n\log\log n}=e^\gamma(1+\Omega_\pm ((\log n)^{-b}) where b is defined constant and \sigma is the sum factors of n.

    I can't seem to find anything which explains what \Omega_\pm means...

    If that's true then that article deserves the purifying heat of the fire and its author(s) deserve to be kindly

    For anyone trying to be the worst maths-paper writer, I bring you the following excellent article of prof. J.S. Milne for authors:
